Re: Lunt Cak B1200 mod question

You wont need to use the wedge Alun, that's an old thread, you will lose too much light.

Your filter order should go UV/IR - Altair - Lunt - Camera.

The ghosts will occur between the Altair and the Lunt, so get as much distance as possible between them. The UV/IR and the Lunt can sit quite close.

Re: Lunt Cak B1200 mod question

Hi ALun,

The Altair filter should work. The Astronimik needs to be the L1 version. You would need to get as must distance as possible between the remnants of the lunt and the ALtair filter to minimise ghosting.

Re: First light solar film white light

Good first light!

Surface blur won't be an issue unless the capture time is in the minutes. Seeing and exposure time are more likely to be the culprits.
